The Boar Bares its Fangs, Zenitsu Sleeps
Inoshishi wa Kiba o Muki, Zenitsu wa Nemuru (猪は牙を剥き、善逸は眠る)
Inside the house, Tanjiro gets separated from Zenitsu. Without Tanjiro by his side, Zenitsu is overcome by fear and despair. Meanwhile, Tanjiro meets the master of the house, the tsuzumi-playing demon, and an odd-looking man wearing a boar’s head mask.
It is the Taisho Period in Japan. Tanjiro, a kindhearted boy who sells charcoal for a living, finds his family slaughtered by a demon. To make matters worse, his younger sister Nezuko, the sole survivor, has been transformed into a demon herself. Though devastated by this grim reality, Tanjiro resolves to become a “demon slayer” so that he can turn his sister back into a human, and kill the demon that massacred his family. A sorrowful tale of siblings in which the fates of humans and demons intertwine… begins now!
